Subject: drivers/misc/atmel_tclib.c: fix a memory leak
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=a844b43ca078d7dd8f0cd13c6f030ec62a996975;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

drivers/misc/atmel_tclib.c: fix a memory leak

request_mem_region() will call kzalloc to allocate memory for struct
resource.  release_resource() unregisters the resource but does not free
the allocated memory, thus use release_mem_region() instead to fix the
memory leak.
